Question
Identify the reactant oxidizsed and the reactant reduced in this chemical reactions 4Fe+3O2----->2FeO3
Solution
In the given chemical reaction, 4Fe + 3O2 --> 2Fe2O3, we can identify the reactant that is oxidized and the reactant that is reduced by looking at the change in oxidation states of the elements involved.
-
Iron (Fe) starts with an oxidation state of 0 (as it is in its elemental form) and ends with an oxidation state of +3 (in Fe2O3). Since the oxidation state increases, Fe is oxidized.
-
Oxygen (O2) starts with an oxidation state of 0 (as it is in its elemental form) and ends with an oxidation state of -2 (in Fe2O3). Since the oxidation state decreases, O2 is reduced.
So, in this reaction, Fe is the reactant that is oxidized and O2 is the reactant that is reduced.
